BAdjusted to reflect current fees.

CFidelity Management & Research Company LLC (FMR) has contractually agreed to reimburse Class A, Class M, Class C, Class I, and Class Z of the fund to the extent that total operating expenses (excluding interest, certain taxes, fees and expenses of the Independent Trustees, proxy and shareholder meeting expenses, extraordinary expenses, and acquired fund fees and expenses (including fees and expenses associated with a wholly owned subsidiary), if any, as well as non-operating expenses such as brokerage commissions and fees and expenses associated with the fund's securities lending program, if applicable), as a percentage of their respective average net assets, exceed 0.62%, 0.62%, 1.37%, 0.37%, and 0.31% (the Expense Caps). If at any time during the current fiscal year expenses for Class A, Class M, Class C, Class I, or Class Z of the fund fall below the Expense Caps, FMR reserves the right to recoup through the end of the fiscal year any expenses that were reimbursed during the current fiscal year up to, but not in excess of, the Expense Caps. These arrangements will remain in effect through May 31, 2026. FMR may not terminate these arrangements before the expiration date without the approval of the Board of Trustees and may extend them in its discretion after that date.

This example helps compare the cost of investing in the fund with the cost of investing in other funds.

Let's say, hypothetically, that the annual return for shares of the fund is 5% and that the fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated and if you hold your shares:

	Class A				Class M				Class C				Class I				Class Z
	Sell All Shares		Hold Shares		Sell All Shares		Hold Shares		Sell All Shares		Hold Shares		Sell All Shares		Hold Shares		Sell All Shares		Hold Shares
1 year	$	461	$	461	$	461	$	461	$	239	$	139	$	38	$	38	$	32	$	32

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 17% of the average value of its portfolio.

Principal Investment Strategies

Normally investing at least 80% of assets in municipal securities (i) whose interest is exempt from federal income tax and (ii) that Fidelity Management & Research Company LLC (FMR) (the Adviser) believes have positive environmental, social and governance (ESG) characteristics. The municipal securities in which the fund invests are normally investment-grade (those of medium and high quality).

Municipal debt securities are issued to raise money for a variety of public and private purposes, including general financing for state and local governments, financing for eligible non-profit organizations, or financing for a specific project or public facility. Municipal debt securities in which the fund invests include securities issued by U.S. territories and possessions, general obligation bonds of municipalities, local or state governments, project or revenue-specific bonds, or pre-refunded or escrowed bonds, municipal money market securities, and synthetic securities. Municipal securities usually pay a fixed, variable, or floating rate of interest, and must repay the amount borrowed, usually at the maturity of the security.

Investment grade securities in which the fund invests include securities or issuers rated at least BBB- or its equivalent by at least one nationally recognized statistical ratings organization (NRSRO), or, if unrated, determined by the Adviser to be of comparable quality.

Effective December 11, 2025, derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives.

Evaluating each security in which the fund invests using both a traditional municipal bond credit, structure and relative value analysis and a consideration of the Adviser's judgment about the security's ESG characteristics. When assessing a security's ESG characteristics and its eligibility for purchase, the Adviser considers the following, where available: (i) the sustainability practices of the security's issuer or obligor, as applicable (each, an "issuer"), based on an evaluation of such issuer's individual ESG profile; (ii) information on a security's use of proceeds; and (iii) any third-party designation as a green, sustainable or sustainability-linked bond. A security's positive ESG characteristics can be determined under any of those three factors.
Using the Adviser's proprietary ESG ratings process to evaluate the current state of an issuer's sustainability practices using a data-driven framework that includes both proprietary and third-party data, and also provide a qualitative forward-looking assessment of an issuer's sustainability outlook provided by the Adviser's fundamental research analysts and ESG team.
The Adviser's ESG ratings of issuers are derived from multiple factors, including an issuer's environmental profile, which may include, but is not limited to, carbon and toxic emissions, water management, waste management, and vulnerability to the physical impacts of climate change. An assessment of an issuer's social profile includes, but is not limited to, its approach to quality health care access, housing affordability, human capital management, community reinvestment, and safety. An assessment of an issuer's governance profile includes, but is not limited to, its principles of management, oversight and transparency, governance efficiency and structure, and consideration of anticompetitive practices. These factors are weighted based on how material the Adviser believes each factor is to an issuer's financial outlook, effectiveness at service delivery, and long-term sustainability, and not all factors may be applicable to all issuers. Issuers with an above average ESG rating as determined by the Adviser are considered to have positive ESG characteristics and well-managed ESG risks.
Assessing a security's use of proceeds by considering factors that provide ESG characteristics, such as energy efficiency, environmentally sustainable management, and providing access to quality health care, essential services and affordable housing. The Adviser will generally consider bonds that finance education, health care, affordable housing, clean energy, municipal water and sewer, public transportation, and designated green bonds, among others, as having positive ESG characteristics.
Managing the fund to have similar overall interest rate risk to the supplemental index (see "Additional Index Information" section of the prospectus).
In addition to focusing on municipal securities with positive ESG characteristics, the Adviser analyzes the credit quality of the issuer, security-specific features, current and potential future valuation, and trading opportunities to select investments.
Normally maintaining a dollar-weighted average maturity between three and 10 years.
Allocating assets across different market sectors and maturities.
Potentially investing more than 25% of total assets in municipal securities that finance similar types of projects.
Employing sustainable investing exclusion criteria to avoid investments in issuers that are directly engaged in, and/or derive significant revenue from, certain industries. Please see "Fund Basics - Investment Details - Sustainable Investing Exclusions" for additional information.

Principal Investment Risks

Municipal Market Volatility.

The municipal market is volatile and can be significantly affected by adverse tax, legislative, or political changes and the financial condition of the issuers of municipal securities.

Sustainability Risk.

Application of Fidelity Management & Research Company LLC's (FMR) (the Adviser) ESG ratings process and/or its sustainable investing exclusion criteria may affect the fund's exposure to certain issuers, sectors, regions, and countries and may affect the fund's performance depending on whether certain investments are in or out of favor. The criteria related to the fund's ESG ratings process and/or adherence to its sustainable investing exclusion criteria may result in the fund forgoing opportunities to buy certain securities when it might otherwise be advantageous to do so, or selling securities for ESG reasons when it might be otherwise disadvantageous for it to do so. As a result, the fund's performance may at times be better or worse than the performance of funds that do not use ESG or sustainability criteria. There are significant differences in interpretations of what it means for an issuer to have positive ESG factors. While the Adviser believes its definitions are reasonable, the portfolio decisions it makes may differ with other investors' or advisers' views. When evaluating an issuer, the Adviser is dependent on information or data obtained through voluntary or third-party reporting that may be incomplete, inaccurate, or unavailable, which could cause the Adviser to incorrectly assess an issuer's business practices.

Interest Rate Changes.

Interest rate increases can cause the price of a debt security to decrease.

Issuer-Specific Changes.

The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

A decline in the credit quality of an issuer or a provider of credit support (such as guarantees) or a maturity-shortening structure (such as demand and put features) for a security can cause the price of a security to decrease.

Management Risk.

The Adviser's application of the fund's strategy criteria may not achieve its intended results. The fund could underperform in comparison to other funds with a similar benchmark or similar objectives and investment strategies.

An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. You could lose money by investing in the fund.

Unlike individual debt securities, which typically pay principal at maturity, the value of an investment in the fund will fluctuate.

Performance

The following information is intended to help you understand the risks of investing in the fund.

The information illustrates the changes in the performance of the fund's shares from year to year and compares the performance of the fund's shares to the performance of a securities market index and an additional index over various periods of time. The additional index has characteristics relevant to the fund's investment strategies. Index descriptions appear in the "Additional Index Information" section of the prospectus. Past performance (before and after taxes) is not an indication of future performance.

Fund Basics

Investment Details

Investment Objective

Fidelity® Sustainable Intermediate Municipal Income Fund seeks as high a level of current income, exempt from federal income tax, as is consistent with the preservation of capital.

Principal Investment Strategies

The Adviser normally invests at least 80% of the fund's assets in municipal securities (i) whose interest is exempt from federal income tax and (ii) that the Adviser believes have positive ESG characteristics. The municipal securities in which the fund invests are normally investment-grade.

Although the Adviser does not currently intend to invest the fund's assets in municipal securities whose interest is subject to federal income tax, the Adviser may invest all of the fund's assets in municipal securities whose interest is subject to the federal alternative minimum tax.

The Adviser evaluates each security in which the fund invests using both a traditional municipal bond credit, structure and relative value analysis and a consideration of the Adviser's judgment about the security's ESG characteristics. When assessing a security's ESG characteristics and its eligibility for purchase, the Adviser considers the following, where available: (i) the sustainability practices of the security's issuer or obligor, as applicable (each, an "issuer"), based on an evaluation of such issuer's individual ESG profile; (ii) information on a security's use of proceeds; and (iii) any third-party designation as a green, sustainable or sustainability-linked bond. A security's positive ESG characteristics can be determined under any of those three factors.

The Adviser's proprietary ESG ratings process is designed to evaluate an issuer's current and future ESG positioning relative to its peers. The process has two components. One component evaluates the current state of an issuer's sustainability practices using a data-driven framework that includes proprietary and third-party (such as HIP Investor, Investortools' CreditScope, and Moody's) data. The other component involves a qualitative forward-looking assessment of an issuer's sustainability outlook provided by the Adviser's fundamental research analysts and ESG team. This qualitative assessment is based on criteria including, but not limited to, the issuer's public sustainability disclosure, the issuer's systems and policies regarding sustainability, and issuer engagement on sustainability issues and opportunities.

The Adviser's ESG ratings of issuers are derived from multiple factors, including an issuer's environmental profile, which may include, but is not limited to, carbon and toxic emissions, water management, waste management, and vulnerability to the physical impacts of climate change. An assessment of an issuer's social profile includes, but is not limited to, its approach to quality health care access, housing affordability, human capital management, community reinvestment, and safety. An assessment of an issuer's governance profile includes, but is not limited to, its principles of management, oversight and transparency, governance efficiency and structure, and consideration of anticompetitive practices. These factors are weighted based on how material the Adviser believes each factor is to an issuer's financial outlook, effectiveness at service delivery, and long-term sustainability, and not all factors may be applicable to all issuers. Based on this process, the Adviser will assign ratings for an issuer's overall ESG performance. Issuers with an above average ESG rating as determined by the Adviser are considered to have positive ESG characteristics and well-managed ESG risks.

In assessing a security's use of proceeds, the Adviser considers factors that provide ESG characteristics, such as energy efficiency, environmentally sustainable management, and providing access to quality health care, essential services and affordable housing. The Adviser will generally consider bonds that finance education, health care, affordable housing, clean energy, municipal water and sewer, public transportation, and designated green bonds, among others, as having positive ESG characteristics.

The Adviser uses the Bloomberg 3-15 Year Blend (2-17) Municipal Bond Index, a market value-weighted index of investment-grade fixed-rate municipal bonds with a certain maturity range, as a guide in structuring the fund and selecting its investments (see "Additional Index Information" section of the prospectus). The Adviser manages the fund to have similar overall interest rate risk to the index.

In addition to its focus on municipal securities with a positive ESG characteristics, the Adviser considers other factors when selecting the fund's investments, including the credit quality of the issuer, security-specific features, current valuation relative to alternatives in the market, short-term trading opportunities resulting from market inefficiencies, and potential future valuation. In managing the fund's exposure to various risks, including interest rate risk, the Adviser considers, among other things, the market's overall risk characteristics, the market's current pricing of those risks, and internal views of potential future market conditions.

In addition, the fund normally maintains a dollar-weighted average maturity between three and 10 years.

The Adviser allocates the fund's assets among different market sectors (for example, general obligation bonds of a state or bonds financing a specific project) and different maturities based on its view of the relative value of each sector or maturity.

The Adviser may invest more than 25% of the fund's total assets in municipal securities that finance similar projects, such as those relating to education, health care, transportation, and utilities.

If the Adviser's strategies do not work as intended, the fund may not achieve its objective.

Description of Principal Security Types

In addition to the security types discussed above, the following describes the types of securities in which the fund invests or may invest principally:

Derivatives are investments whose values are tied to an underlying asset, instrument, currency, or index. Derivatives include futures, options, forwards, and swaps, such as interest rate swaps (exchanging a floating rate for a fixed rate), total return swaps (exchanging a floating rate for the total return of an index, security, or other instrument or investment) and credit default swaps (buying or selling credit default protection).

Forward-settling securities involve a commitment to purchase or sell specific securities when issued, or at a predetermined price or yield. Payment and delivery take place after the customary settlement period.

Sustainable Investing Exclusions

As part of its investment approach, the fund also applies broad criteria ("exclusion criteria") that seek to exclude issuers that are directly engaged in, and/or derive significant revenue from, certain industries or product lines. At present, these include: civilian semi-automatic firearms; tobacco production, or bonds issued against the proceeds of tobacco settlements; for-profit prisons; controversial weapons (e.g., cluster munitions, land mines, biological/chemical weapons, blinding lasers, and incendiary weapons); and thermal coal production and/or mining.

In determining whether an issuer is directly engaged in, and/or derives significant revenue from a particular industry or product line, the fund may use revenue thresholds (e.g., issuers that derive more than 5% of revenue from thermal coal production and/or mining) and/or categorical exclusions (e.g., issuers that derive any revenue from the operation of private prisons), depending on the industry or product line. The exclusion criteria are based in whole or in part on data provided by one or more third-party vendor(s) and are, therefore, subject to each vendor's industry and product line definitions (which may vary from those of the Adviser) and data limitations. The Adviser, in its sole discretion, retains the right not to use data provided by third-party vendors where it deems the data not representative of an issuer's current business operations. In such cases, or where data on specific issuers may not be available from third-party vendors, the Adviser may make reasonable estimates or otherwise exercise its discretion.

The fund's exclusion criteria may be updated periodically to, among other things, add or remove certain industries or product lines from the screening process, revise the revenue thresholds and categorical exclusions applicable to such activities, or change particular industries or product lines from a categorical exclusion to a revenue threshold, or vice versa. Once the Adviser determines that an issuer is not subject to the fund's exclusion criteria, the Adviser then employs the sustainability strategy discussed above. In addition, the fund may invest in third-party investment products (e.g., mutual funds, ETFs, and/or index futures) that apply different or no exclusion criteria or sustainable investment strategies.

The implementation of the sustainability strategy (or strategies) is conducted alongside traditional fundamental, bottom-up financial analysis of individual issuers, using traditional fundamental metrics and/or traditional quantitative metrics. The Adviser may also engage in dialogues with the issuer's management teams to further inform investment decision-making and to foster best corporate governance practices using its fundamental and sustainability analysis. In addition, the fund may invest in an issuer prior to completion of the sustainability analysis or without engaging with the issuer's management.

Principal Investment Risks

Many factors affect the fund's performance. Developments that disrupt global economies and financial markets, such as public health emergencies, military conflicts, terrorism, government restrictions, political changes, and environmental disasters, may significantly affect the fund's investment performance. The fund's share price and yield change daily based on changes in market conditions and interest rates and in response to other economic, political, or financial developments. The fund's reaction to these developments will be affected by the types and maturities of securities in which the fund invests, the financial condition, industry and economic sector, and geographic location of an issuer, and the fund's level of investment in the securities of that issuer. Unlike individual debt securities, which typically pay principal at maturity, the value of an investment in the fund will fluctuate. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money by investing in the fund.

The following factors can significantly affect the fund's performance:

Municipal Market Volatility. Municipal securities can be significantly affected by political changes as well as uncertainties in the municipal market related to taxation, legislative changes, or the rights of municipal security holders. Because many municipal securities are issued to finance similar projects, especially those relating to education, health care, transportation, and utilities, conditions in those sectors can affect the overall municipal market. Budgetary constraints of local, state, and federal governments upon which the issuers may be relying for funding may also impact municipal securities. In addition, changes in the financial condition of an individual municipal insurer can affect the overall municipal market, and market conditions may directly impact the liquidity and valuation of municipal securities.

Sustainability Risk. Application of FMR's ESG ratings process and/or its sustainable investing exclusion criteria may affect the fund's exposure to certain issuers, sectors, regions, and countries and may affect the fund's performance depending on whether certain investments are in or out of favor. The criteria related to the fund's ESG ratings process and/or adherence to its sustainable investing exclusion criteria may result in the fund forgoing opportunities to buy certain securities when it might otherwise be advantageous to do so, or selling securities for ESG reasons when it might be otherwise disadvantageous for it to do so. As a result, the fund's performance may at times be better or worse than the performance of funds that do not use ESG or sustainability criteria. There are significant differences in interpretations of what it means for an issuer to have positive ESG factors. While the Adviser believes its definitions are reasonable, the portfolio decisions it makes may differ with other investors' or advisers' views. Socially responsible norms differ by country and region, and an issuer's ESG factors or the Adviser's assessment of such may change over time. A fund may invest in issuers that do not reflect the beliefs and values of any particular investor. When conducting the ESG ratings process of an issuer or compiling and maintaining the sustainable investing exclusion list, the Adviser may rely on information or data obtained through voluntary or third-party reporting that may be incomplete, inaccurate, or unavailable, which could cause the Adviser to incorrectly assess an issuer's business practices with respect to ESG or to incorrectly include or exclude an issuer on or from its sustainable investing exclusion list. The sustainable investing exclusion list criteria are based in whole or in part on data provided by one or more third-party vendor(s) and are, therefore, subject to each vendor's industry and product line definitions (which may vary from those of the Adviser) and data limitations. Data used in applying the exclusion criteria may include inputs self-disclosed by companies as well as estimates where public disclosures are unavailable. Certain investments may be dependent on U.S. and foreign government policies, including tax incentives and subsidies, which may change without notice. A fund's investments in certain issuers may be susceptible to various factors that may impact their businesses or operations, including costs associated with government budgetary constraints that impact publicly funded projects and initiatives, the effects of general economic conditions throughout the world, increased competition from other providers of services, unfavorable tax laws or accounting policies and high leverage.

Interest Rate Changes. Debt securities, including money market securities, have varying levels of sensitivity to changes in interest rates. In general, the price of a debt security can fall when interest rates rise and can rise when interest rates fall. Securities with longer maturities can be more sensitive to interest rate changes, meaning the longer the maturity of a security, the greater the impact a change in interest rates could have on the security's price. Short-term and long-term interest rates do not necessarily move in the same amount or the same direction. Short-term securities tend to react to changes in short-term interest rates, and long-term securities tend to react to changes in long-term interest rates. Securities with floating interest rates can be less sensitive to interest rate changes, but may decline in value if their interest rates do not rise as much as interest rates in general. In market environments where interest rates are rising, issuers may be less willing or able to make principal and/or interest payments on securities when due.

Issuer-Specific Changes. Changes in the financial condition of an issuer or counterparty, changes in specific economic or political conditions that affect a particular type of security or issuer, and changes in general economic or political conditions can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's credit quality or value. Entities providing credit support (such as guarantees) or a maturity-shortening structure (such as demand and put features) also can be affected by these types of changes, and if the structure of a security fails to function as intended, the security could decline in value. Lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds) tend to be particularly sensitive to these changes. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the taxation supporting the project or assets or the inability to collect revenues for the project or from the assets. If the Internal Revenue Service (IRS) determines an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could become taxable and the security could decline significantly in value.

Lower-quality debt securities involve greater risk of default or price changes due to changes in the credit quality of the issuer. The value of lower-quality debt securities often fluctuates in response to company, political, or economic developments and can decline significantly over short as well as long periods of time or during periods of general or regional economic difficulty. Lower-quality debt securities can be thinly traded or have restrictions on resale, making them difficult to sell at an acceptable price, and often are considered to be speculative.

Generally, the fund purchases municipal securities whose interest, in the opinion of bond counsel, is free from federal income tax. Neither the Adviser nor the fund guarantees that this opinion is correct, and there is no assurance that the IRS will agree with bond counsel's opinion. Issuers or other parties generally enter into covenants requiring continuing compliance with federal tax requirements to preserve the tax-free status of interest payments over the life of the security. If at any time the covenants are not complied with, or if the IRS otherwise determines that the issuer did not comply with relevant tax requirements, interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued. For certain types of structured securities, the tax status of the pass-through of tax-free income may also be based on the federal tax treatment of the structure.

Leverage Risk. Derivatives and forward-settling securities involve leverage because they can provide investment exposure in an amount exceeding the initial investment. Leverage can magnify investment risks and cause losses to be realized more quickly. A small change in the underlying asset, instrument, or index can lead to a significant loss. Forward-settling securities also involve the risk that a security will not be issued, delivered, or paid for when anticipated. Government legislation or regulation could affect the use of these transactions and could limit a fund's ability to pursue its investment strategies.

Management Risk. The Adviser's application of the fund's strategy criteria may not achieve its intended results. The fund could underperform in comparison to other funds with a similar benchmark or similar objectives and investment strategies.

In response to market, economic, political, or other conditions, a fund may temporarily use a different investment strategy for defensive purposes. If the fund does so, different factors could affect its performance, and the fund could distribute income subject to federal income tax.

Other Investment Strategies

In addition to the principal investment strategies discussed above, the Adviser may invest the fund's assets in lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds). The Adviser may invest the fund's assets in municipal debt securities by investing in other funds.

The Adviser may also engage in transactions that have a leveraging effect on the fund, including investments in derivatives, regardless of whether the fund may own the asset, instrument, or components of the index underlying the derivative, and forward-settling securities. The fund's derivative investments may include interest rate swaps, total return swaps, credit default swaps, and futures contracts (both long and short positions) on securities and indexes. Depending on the Adviser's outlook and market conditions, the Adviser may engage in these transactions to increase or decrease the fund's exposure to changing security prices, interest rates, credit qualities, or other factors that affect security values, or to gain or reduce exposure to an asset, instrument, or index.

Fundamental Investment Policies

The following is fundamental, that is, subject to change only by shareholder approval:

Fidelity® Sustainable Intermediate Municipal Income Fund normally invests at least 80% of its assets in municipal securities whose interest is exempt from federal income tax.

Non-Fundamental Investment Policies

The fund's investment objective is non-fundamental and may be changed without shareholder approval.

Shareholder Notice

The following is subject to change only upon 60 days' prior notice to shareholders:

Fidelity® Sustainable Intermediate Municipal Income Fund normally invests at least 80% of its assets in municipal securities that the Adviser believes have positive ESG characteristics.

Valuing Shares

The fund is open for business each day the NYSE is open.

The NAV is the value of a single share. Fidelity normally calculates NAV as of the close of business of the NYSE, normally 4:00 p.m. Eastern time. The fund's assets normally are valued as of this time for the purpose of computing NAV. Fidelity calculates NAV separately for each class of shares of a multiple class fund.

NAV is not calculated and the fund will not process purchase and redemption requests submitted on days when the fund is not open for business. The time at which shares are priced and until which purchase and redemption orders are accepted may be changed as permitted by the Securities and Exchange Commission (SEC).

To the extent that the fund's assets are traded in other markets on days when the fund is not open for business, the value of the fund's assets may be affected on those days. In addition, trading in some of the fund's assets may not occur on days when the fund is open for business.

NAV is calculated using the values of other open-end funds, if any, in which the fund invests (referred to as underlying funds). Shares of underlying funds are valued at their respective NAVs. Other assets are valued primarily on the basis of market quotations, official closing prices, or information furnished by a pricing service. Certain short-term securities are valued on the basis of amortized cost. If market quotations, official closing prices, or information furnished by a pricing service are not readily available or, in the Adviser's opinion, are deemed unreliable for a security, then that security will be fair valued in good faith by the Adviser in accordance with applicable fair value pricing policies. For example, if, in the Adviser's opinion, a security's value has been materially affected by events occurring before a fund's pricing time but after the close of the exchange or market on which the security is principally traded, then that security will be fair valued in good faith by the Adviser in accordance with applicable fair value pricing policies. Fair value pricing will be used for high yield debt securities when available pricing information is determined to be stale or for other reasons not to accurately reflect fair value.

Arbitrage opportunities may exist when trading in a portfolio security or securities is halted and does not resume before a fund calculates its NAV. These arbitrage opportunities may enable short-term traders to dilute the NAV of long-term investors. Securities trading in overseas markets, if applicable, present time zone arbitrage opportunities when events affecting portfolio security values occur after the close of the overseas markets but prior to the close of the U.S. market. Fair valuation of a fund's portfolio securities can serve to reduce arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing policies will prevent dilution of NAV by short-term traders.

Policies regarding excessive trading may not be effective to prevent short-term NAV arbitrage trading, particularly in regard to omnibus accounts.

Fair value pricing is based on subjective judgments and it is possible that the fair value of a security may differ materially from the value that would be realized if the security were sold.

Shareholder Information

Additional Information about the Purchase and Sale of Shares

As used in this prospectus, the term "shares" generally refers to the shares offered through this prospectus.

General Information

Ways to Invest

You may buy or sell shares through a retirement account or an investment professional. When you invest through a retirement account or an investment professional, the procedures for buying, selling, and exchanging shares and the account features, policies, and fees may differ. Additional fees may apply to your investment in shares, including a transaction fee if you buy or sell shares through a broker or other investment professional. Your broker may also require you to pay brokerage commissions on purchases and sales of certain share classes of the fund.

Information on Placing Orders

You should include the following information with any order:

Your name
Your account number
Type of transaction requested
Name(s) of fund(s) and class(es)
Dollar amount or number of shares

Certain methods of contacting Fidelity may be unavailable or delayed (for example, during periods of unusual market activity). In addition, the level and type of service available may be restricted.

Frequent Purchases and Redemptions

The fund may reject for any reason, or cancel as permitted or required by law, any purchase or exchange, including transactions deemed to represent excessive trading, at any time.

Excessive trading of fund shares can harm shareholders in various ways, including reducing the returns to long-term shareholders by increasing costs to the fund (such as brokerage commissions or spreads paid to dealers who sell money market instruments), disrupting portfolio management strategies, and diluting the value of the shares in cases in which fluctuations in markets are not fully priced into the fund's NAV.

The fund reserves the right at any time to restrict purchases or exchanges or impose conditions that are more restrictive on excessive trading than those stated in this prospectus.

Excessive Trading Policy

The Board of Trustees has adopted policies designed to discourage excessive trading of fund shares. Excessive trading activity in a fund is measured by the number of roundtrip transactions in a shareholder's account and each class of a multiple class fund is treated separately. A roundtrip transaction occurs when a shareholder sells fund shares (including exchanges) within 30 days of the purchase date.

Shareholders with two or more roundtrip transactions in a single fund within a rolling 90-day period will be blocked from making additional purchases or exchange purchases of the fund for 85 days. Shareholders with four or more roundtrip transactions across all Fidelity® funds within any rolling 12-month period will be blocked for at least 85 days from additional purchases or exchange purchases across all Fidelity® funds. Any roundtrip within 12 months of the expiration of a multi-fund block will initiate another multi-fund block. Repeat offenders may be subject to long-term or permanent blocks on purchase or exchange purchase transactions in any account under the shareholder's control at any time. In addition to enforcing these roundtrip limitations, the fund may in its discretion restrict, reject, or cancel any purchases or exchanges that, in the Adviser's opinion, may be disruptive to the management of the fund or otherwise not be in the fund's interests.

Exceptions

The following transactions are exempt from the fund's excessive trading policy described above: (i) systematic withdrawal and/or contribution programs, (ii) mandatory retirement distributions, (iii) transactions initiated by a plan sponsor or sponsors of certain employee benefit plans or other related accounts, (iv) transactions within a qualified advisory program, and (v) transactions initiated by the trustee or adviser to a donor-advised charitable gift fund, qualified fund of funds, or other strategy funds.

A qualified advisory program is one that demonstrates to Fidelity that the program has investment strategies and trading policies designed to protect the interests of long-term investors and meets specific criteria outlined by Fidelity.

A qualified fund of funds is a mutual fund, qualified tuition program, or other strategy fund consisting of qualified plan assets that either applies the fund's excessive trading policies to shareholders at the fund of funds level, or demonstrates that the fund of funds has an investment strategy coupled with policies designed to control frequent trading that are reasonably likely to be effective as determined by the fund's Treasurer. Some qualified funds of funds may be exempt, as determined by the fund's Treasurer, from monitoring frequent trading based on the nature of the fund of funds.

Fidelity may choose not to monitor transactions below certain dollar value thresholds.

Omnibus Accounts

Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple investors, are a common form of holding shares among retirement plans and financial intermediaries such as brokers, advisers, and third-party administrators. Individual trades in omnibus accounts are often not disclosed to the fund, making it difficult to determine whether a particular shareholder is engaging in excessive trading. Excessive trading in omnibus accounts is likely to go undetected by the fund and may increase costs to the fund and disrupt its portfolio management.

Under policies adopted by the Board of Trustees, intermediaries will be permitted to apply the fund's excessive trading policy (described above), or their own excessive trading policy if approved by the Adviser. In these cases, the fund will typically not request or receive individual account data but will rely on the intermediary to monitor trading activity in good faith in accordance with its or the fund's policies. Reliance on intermediaries increases the risk that excessive trading may go undetected. For other intermediaries, the fund will generally monitor trading activity at the omnibus account level to attempt to identify disruptive trades. The fund may request transaction information, as frequently as daily, from any intermediary at any time, and may apply the fund's policy to transactions that exceed thresholds established by the Board of Trustees. The fund may prohibit purchases of fund shares by an intermediary or by some or all of any intermediary's clients. There is no assurance that the Adviser will request data with sufficient frequency to detect or deter excessive trading in omnibus accounts effectively.

If you purchase or sell fund shares through a financial intermediary, you may wish to contact the intermediary to determine the policies applicable to your account.

Retirement Plans

For employer-sponsored retirement plans, only participant directed exchanges count toward the roundtrip limits. Employer-sponsored retirement plan participants whose activity triggers a purchase or exchange block will be permitted one trade every calendar quarter. In the event of a block, employer and participant contributions and loan repayments by the participant may still be invested in the fund.

Other Information about the Excessive Trading Policy

The fund's Treasurer is authorized to suspend the fund's policies during periods of severe market turbulence or national emergency. The fund reserves the right to modify its policies at any time without prior notice.

The fund does not knowingly accommodate frequent purchases and redemptions of fund shares by investors, except to the extent permitted by the policies described above.

As described in "Valuing Shares," the fund also uses fair value pricing to help reduce arbitrage opportunities available to short-term traders. There is no assurance that the fund's excessive trading policy will be effective, or will successfully detect or deter excessive or disruptive trading.

Buying Shares

Eligibility

Shares are generally available only to investors residing in the United States.

Each class of the fund has different expenses and features, as described in the applicable prospectus. Investors eligible to purchase one class of shares may also be eligible to purchase other classes of shares of the fund. Your investment professional, as applicable, can help you choose the class of shares that best suits your investment needs. However, plan participants may purchase only the classes of shares that are eligible for sale and available through their plan. Certain classes may have higher expenses than those offered by the plan.

Investors may be able to purchase Class Z in other circumstances. Please contact Fidelity or your investment professional for more information about Class Z shares.

There is no minimum balance or purchase minimum for fund shares.

Price to Buy

The price to buy one share of Class A or Class M is its offering price or its NAV, depending on whether you pay a front-end sales charge.

The price to buy one share of Class C, Class I, or Class Z is its NAV. Class C shares are sold without a front-end sales charge, but may be subject to a CDSC upon redemption. Class I and Class Z shares are sold without a sales charge.

If you pay a front-end sales charge, your price will be Class A's or Class M's offering price. When you buy Class A or Class M shares at the offering price, Fidelity deducts the appropriate sales charge and invests the rest in Class A or Class M shares of the fund. If you qualify for a front-end sales charge waiver, your price will be Class A's or Class M's NAV.

The offering price of Class A or Class M is its NAV plus the sales charge. The offering price is calculated by dividing Class A's or Class M's NAV by the difference between one and the applicable front-end sales charge percentage and rounding to the nearest cent.

The dollar amount of the sales charge for Class A or Class M is the difference between the offering price of the shares purchased and the NAV of those shares. Since the offering price per share is calculated to the nearest cent using standard rounding criteria, the percentage sales charge you actually pay may be higher or lower than the sales charge percentages shown in this prospectus due to rounding. The impact of rounding may vary with the amount of your investment and the size of the class's NAV.

Shares will be bought at the offering price or NAV, as applicable, next calculated after an order is received in proper form.

It is the responsibility of your investment professional to transmit your order to buy shares to Fidelity before the close of business on the day you place your order.

The fund has authorized certain intermediaries to accept orders to buy shares on its behalf. When authorized intermediaries receive an order in proper form, the order is considered as being placed with the fund, and shares will be bought at the offering price or NAV, as applicable, next calculated after the order is received by the authorized intermediary. If applicable, orders by funds of funds for which Fidelity serves as investment manager will be treated as received by the fund at the same time that the corresponding orders are received in proper form by the funds of funds.

The fund may stop offering shares completely or may offer shares only on a limited basis, for a period of time or permanently.

If your payment is not received and collected, your purchase may be canceled and you could be liable for any losses or fees the fund or Fidelity has incurred.

Shares can be bought or sold through investment professionals using an automated order placement and settlement system that guarantees payment for orders on a specified date.

Certain financial institutions that meet creditworthiness criteria established by FDC may enter confirmed purchase orders on behalf of customers by phone, with payment to follow no later than close of business on the next business day. If payment is not received by that time, the order will be canceled and the financial institution will be liable for any losses.

Under applicable anti-money laundering rules and other regulations, purchase orders may be suspended, restricted, or canceled and the monies may be withheld.

Selling Shares

The price to sell one share of Class A, Class M, or Class C is its NAV, minus any applicable CDSC. The price to sell one share of Class I or Class Z is its NAV.

Shares will be sold at the NAV next calculated after an order is received in proper form, minus any applicable CDSC.

Normally, redemptions will be processed by the next business day, but it may take up to seven days to pay the redemption proceeds if making immediate payment would adversely affect the fund.

It is the responsibility of your investment professional to transmit your order to sell shares to Fidelity before the close of business on the day you place your order.

The fund has authorized certain intermediaries to accept orders to sell shares on its behalf. When authorized intermediaries receive an order in proper form, the order is considered as being placed with the fund, and shares will be sold at the NAV next calculated after the order is received by the authorized intermediary, minus any applicable CDSC. If applicable, orders by funds of funds for which Fidelity serves as investment manager will be treated as received by the fund at the same time that the corresponding orders are received in proper form by the funds of funds.

See "Policies Concerning the Redemption of Fund Shares" below for additional redemption information.

A signature guarantee is designed to protect you and Fidelity from fraud. Fidelity may require that your request be made in writing and include a signature guarantee in certain circumstances, such as:

When you wish to sell more than $100,000 worth of shares.
When the address on your account (record address) has changed within the last 15 days or you are requesting that a check be mailed to an address different than the record address.
When you are requesting that redemption proceeds be paid to someone other than the account owner.
In certain situations when the redemption proceeds are being transferred to a Fidelity® brokerage or mutual fund account with a different registration.

You should be able to obtain a signature guarantee from a bank, broker-dealer, credit union (if authorized under state law), securities exchange or association, clearing agency, or savings association. A notary public cannot provide a signature guarantee.

When you place an order to sell shares, note the following:

Redemption proceeds (other than exchanges) may be delayed until money from prior purchases sufficient to cover your redemption has been received and collected.

Redemptions may be suspended or payment dates postponed when the NYSE is closed (other than weekends or holidays), when trading on the NYSE is restricted, or as permitted by the SEC.

Redemption proceeds may be paid in securities or other property rather than in cash if the Adviser determines it is in the best interests of the fund.
You will not receive interest on amounts represented by uncashed redemption checks.

Under applicable anti-money laundering rules and other regulations, redemption requests may be suspended, restricted, canceled, or processed and the proceeds may be withheld.

Class Z: When your relationship with your managed account provider is terminated, your shares may be sold at the NAV next calculated, in which case the redemption proceeds will remain in your account pending your instruction.

Policies Concerning the Redemption of Fund Shares

If your account is held directly with a fund, the length of time that a fund typically expects to pay redemption proceeds depends on the method you have elected to receive such proceeds. A fund typically expects to make payment of redemption proceeds by wire, automated clearing house (ACH) or by issuing a check by the next business day following receipt of a redemption order in proper form. Proceeds from the periodic and automatic sale of shares of a Fidelity® money market fund that are used to buy shares of another Fidelity® fund are settled simultaneously.

If your account is held through an intermediary, the length of time that a fund typically expects to pay redemption proceeds depends, in part, on the terms of the agreement in place between the intermediary and a fund. For redemption proceeds that are paid either directly to you from a fund or to your intermediary for transmittal to you, a fund typically expects to make payments by wire, by ACH or by issuing a check on the next business day following receipt of a redemption order in proper form from the intermediary by a fund. Redemption orders that are processed through investment professionals that utilize the National Securities Clearing Corporation will generally settle one to three business days following receipt of a redemption order in proper form.

As noted elsewhere, payment of redemption proceeds may take longer than the time a fund typically expects and may take up to seven days from the date of receipt of the redemption order as permitted by applicable law.

Redemption Methods Available. Generally a fund expects to pay redemption proceeds in cash. To do so, a fund typically expects to satisfy redemption requests either by using available cash (or cash equivalents) or by selling portfolio securities. On a less regular basis, a fund may also satisfy redemption requests by utilizing one or more of the following sources, if permitted: borrowing from another Fidelity® fund; drawing on an available line or lines of credit from a bank or banks; or using reverse repurchase agreements. These methods may be used during both normal and stressed market conditions.

In addition to paying redemption proceeds in cash, a fund reserves the right to pay part or all of your redemption proceeds in readily marketable securities instead of cash (redemption in-kind). Redemption in-kind proceeds will typically be made by delivering the selected securities to the redeeming shareholder within seven days after the receipt of the redemption order in proper form by a fund.

Converting Shares

The fund will automatically convert your class of shares of the fund to Class Z shares, if Class Z of the fund is available under your plan.

The fund may convert your Class Z shares to another class of shares of the fund, including classes of shares not offered in this prospectus that are available under your plan, if your plan is no longer eligible to offer Class Z. Information on the other classes of shares of the fund can be found in that class's prospectus. Investors will be notified in writing before any such conversion to another class.

A conversion will be based on the respective NAVs of the two classes, without the imposition of any fees, on the trade date of the conversion.

Conversion Feature. After a maximum of eight years from the initial date of purchase, Class C shares convert automatically to Class A shares of a fund. Conversion to Class A shares will be made at NAV. At the time of conversion, a portion of the Class C shares bought through the reinvestment of dividends or capital gains (Dividend Shares) will also convert to Class A shares. The portion of Dividend Shares that will convert is determined by the ratio of your converting Class C non-Dividend Shares to your total Class C non-Dividend Shares. A fund may convert shares sooner in certain circumstances. A shorter holding period may also apply depending on your intermediary. Please see "Sales Charge Waiver Policies Applied by Certain Intermediaries" in the "Appendix" section of this prospectus.

A conversion between share classes of the same fund is a non-taxable event.

Exchanging Shares

An exchange involves the redemption of all or a portion of the shares of one fund and the purchase of shares of another fund.

As a Class A shareholder, you have the privilege of exchanging Class A shares for the same class of shares of other Fidelity® funds that offer Advisor classes of shares at NAV or for Daily Money Class shares of Fidelity® funds that offer Daily Money Class shares.

As a Class M shareholder, you have the privilege of exchanging Class M shares for the same class of shares of other Fidelity® funds that offer Advisor classes of shares at NAV or for Advisor M Class shares of Fidelity® Government Money Market Fund. If you purchased your Class M shares through certain investment professionals that have signed an agreement with FDC, you also have the privilege of exchanging your Class M shares for shares of Fidelity® Capital Appreciation Fund.

As a Class C shareholder, you have the privilege of exchanging Class C shares for the same class of shares of other Fidelity® funds that offer Advisor classes of shares or for Advisor C Class shares of Fidelity® Treasury Money Market Fund.

As a Class I shareholder, you have the privilege of exchanging Class I shares for the same class of shares of other Fidelity® funds that offer Advisor classes of shares or for shares of Fidelity® funds.

As a Class Z shareholder, you have the privilege of exchanging Class Z shares for the same class of shares of other Fidelity® funds that offer Advisor classes of shares or Class Z shares of other Fidelity® funds available through your employee benefit plan, or if the Fidelity® fund does not offer Class Z shares, then other classes of the Fidelity® fund that are available through your plan.

Through your investment professional, you may also move between certain share classes of the same fund. For more information, see the Statement of Additional Information (SAI) or consult your investment professional.

However, you should note the following policies and restrictions governing exchanges:

The exchange limit may be modified for accounts held by certain institutional retirement plans to conform to plan exchange limits and Department of Labor regulations. See your retirement plan materials for further information.
The fund may refuse any exchange purchase for any reason. For example, the fund may refuse exchange purchases by any person or group if, in the Adviser's judgment, the fund would be unable to invest the money effectively in accordance with its investment objective and policies, or would otherwise potentially be adversely affected.
An exchange of shares is not subject to any applicable CDSCs.
Before any exchange, read the prospectus for the shares you are purchasing, including any purchase and sale requirements.
The shares you are acquiring by exchange must be available for sale in your state.
Exchanges may have tax consequences for you if you own shares in a taxable account.
If you are exchanging between accounts that are not registered in the same name, address, and taxpayer identification number (TIN), there may be additional requirements.
Under applicable anti-money laundering rules and other regulations, exchange requests may be suspended, restricted, canceled, or processed and the proceeds may be withheld.

The fund may terminate or modify exchange privileges in the future.

Other funds may have different exchange restrictions and minimums. Check each fund's prospectus for details.

Rollover IRAs

Class Z shares generally are not available to IRA rollover accounts. Assets from retirement plans may be invested in other class(es) of shares of the fund through an IRA rollover, including class(es) of shares not offered in this prospectus. Each class of the fund has different expenses and features and may have higher expenses than Class Z shares. Information on the other class(es) of shares of the fund, including any class expenses and features, can be found in the applicable class's prospectus.

Please contact your investment professional for more information.

In addition, the fund reserves the right to involuntarily redeem an account in the case of: (i) actual or suspected threatening conduct or actual or suspected fraudulent, illegal or suspicious activity by the account owner or any other individual associated with the account; or (ii) the failure of the account owner to provide information to the fund related to opening the accounts. Your shares will be sold at the NAV, minus any applicable shareholder fees, calculated on the day Fidelity closes your fund position.

Fidelity may charge a fee for certain services, such as providing historical account documents.

The fund processes purchase and redemption requests only on days it is open for business.

When you buy shares, your method of payment will determine when dividends begin to accrue. For example, shares purchased through an investment professional using the National Securities Clearing Corporation generally begin to earn dividends on the day the fund receives payment for those shares. Shares purchased through an investment professional by any other method generally begin to earn dividends on the first business day following the day the fund receives payment. If you purchase your shares directly from the fund by check or wire, those shares generally begin to earn dividends on the first business day following the day you placed your purchase order.

Shares sold through an investment professional using the National Securities Clearing Corporation generally earn dividends until, but not including, the day redemption proceeds are processed. Shares sold through an investment professional by any other method generally earn dividends until, but not including, the first business day following the day redemption proceeds are processed. Shares sold other than through an investment professional generally earn dividends until, but not including, the first business day following the day of redemption.

Exchange requests will be processed only when both funds are open for business.

Distribution Options

When you open an account, specify how you want to receive your distributions. The following distribution options are available:

1. Reinvestment Option.

Any dividends and capital gain distributions will be automatically reinvested in additional shares. If you do not indicate a choice, you will be assigned this option.

2. Income-Earned Option.

Any capital gain distributions will be automatically reinvested in additional shares. Any dividends will be paid in cash.

3. Cash Option.

Any dividends and capital gain distributions will be paid in cash.

4. Directed Dividends® Option.

Any dividends will be automatically invested in the same class of shares of another identically registered Fidelity® fund. Any capital gain distributions will be automatically invested in the same class of shares of another identically registered Fidelity® fund, automatically reinvested in additional shares of the fund, or paid in cash.

Not all distribution options may be available for every account and certain restrictions may apply. If the option you prefer is not listed on your account application, or if you want to change your current option, contact Fidelity or your investment professional directly.

If you elect to receive distributions paid in cash by check and the U.S. Postal Service does not deliver your checks, your distribution option may be converted to the Reinvestment Option. You will not receive interest on amounts represented by uncashed distribution checks.

Any dividends and capital gain distributions paid to retirement plan participants will be automatically reinvested.

Tax Consequences

As with any investment, your investment in the fund could have tax consequences for you (for non-retirement accounts).

Taxes on Distributions

The fund seeks to earn income and pay dividends exempt from federal income tax.

Income exempt from federal income tax may be subject to state or local tax. A portion of the dividends you receive may be subject to federal and state income taxes and may also be subject to the federal alternative minimum tax. You may also receive taxable distributions attributable to the fund's sale of bonds.

For federal tax purposes, certain distributions, including distributions of short-term capital gains and gains on the sale of bonds characterized as market discount, are taxable to you as ordinary income, while certain distributions of long-term capital gains are taxable to you generally as capital gains.

If you buy shares when a fund has realized but not yet distributed income or capital gains, you will be "buying a dividend" by paying the full price for the shares and then receiving a portion of the price back in the form of a potentially taxable distribution.

Any taxable distributions you receive from the fund will normally be taxable to you when you receive them, regardless of your distribution option.

If you elect to receive distributions in cash or to invest distributions automatically in the same class of shares of another Fidelity® fund that offers Advisor classes of shares or shares of Fidelity® funds, you will receive certain December distributions in January, but those distributions will be taxable as if you received them on December 31.

Distributions by the fund to tax-advantaged retirement plan accounts are not taxable currently (but you may be taxed later, upon withdrawal of your investment from such account).

Taxes on Transactions

Your redemptions, including exchanges, may result in a capital gain or loss for federal tax purposes. A capital gain or loss on your investment in the fund generally is the difference between the cost of your shares and the price you receive when you sell them.

Exchanges within a tax-advantaged retirement plan account will not result in a capital gain or loss for federal tax purposes. Please consult your tax advisor regarding the tax treatment of distributions from a tax-advantaged retirement plan account.

The SAI provides additional information about the compensation of, any other accounts managed by, and any fund shares held by the portfolio manager(s).

From time to time a manager, analyst, or other Fidelity employee may express views regarding a particular company, security, industry, or market sector. The views expressed by any such person are the views of only that individual as of the time expressed and do not necessarily represent the views of Fidelity or any other person in the Fidelity organization. Any such views are subject to change at any time based upon market or other conditions and Fidelity disclaims any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of any fund.

Advisory Fee(s)

Each class of the fund pays a management fee to the Adviser.

A different management fee rate may be applicable to each class of the fund. The difference between classes is the result of separate arrangements for class-level services and/or waivers of certain expenses. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund's assets, which do not vary by class.

The management fee is calculated and paid to the Adviser every month.

When determining a class's management fee, a mandate rate is calculated based on the monthly average net assets of a group of funds advised by FMR within a designated asset class. A discount rate is subtracted from the mandate rate once the fund's monthly average net assets reach a certain level. The mandate rate and discount rate may vary by class.

The annual management fee rate for each class of shares of the fund offered through this prospectus is the lesser of (1) the class's mandate rate reduced by the class's discount rate (if applicable) or (2) the amount listed below:

Fund	Class A	Class M	Class C	Class I	Class Z
Fidelity® Sustainable Intermediate Municipal Income Fund	0.48%	0.51%	0.52%	0.52%	0.39%

One-twelfth of the management fee rate for a class is applied to the average net assets of the class for the month, giving a dollar amount which is the management fee for the class for that month.

The management fee, as a percentage of each class's average net assets, for the fiscal year ended January 31, 2025, for the fund is shown in the following table. Because a class's management fee rate may fluctuate, a class's management fee may be higher or lower in the future.

Fund/Class	Management Fee Rate
Fidelity® Sustainable Intermediate Municipal Income Fund/Class A	0.47%A
Fidelity® Sustainable Intermediate Municipal Income Fund/Class M	0.50%A
Fidelity® Sustainable Intermediate Municipal Income Fund/Class C	0.51%A
Fidelity® Sustainable Intermediate Municipal Income Fund/Class I	0.51%A
Fidelity® Sustainable Intermediate Municipal Income Fund/Class Z	0.39%A

A Effective March 1, 2024, the fund's management contract was amended to incorporate administrative services previously covered under separate services agreements. The amended contract incorporates a management fee rate that may vary by class. The Adviser or an affiliate pays certain expenses of managing and operating the fund out of each class's management fee. Prior to March 1, 2024, the fund's management fee consisted of a group fee rate component plus an individual fund fee rate.

The Adviser pays FMR Investment Management (UK) Limited, Fidelity Management & Research (Hong Kong) Limited, and Fidelity Management & Research (Japan) Limited for providing sub-advisory services.

The basis for the Board of Trustees approving the management contract and sub-advisory agreements for the fund is available in the fund's Form N-CSR report for the fiscal period ended January 31, 2025.

From time to time, the Adviser or its affiliates may agree to reimburse or waive certain fund expenses while retaining the ability to be repaid if expenses fall below the specified limit prior to the end of the fiscal year.

Reimbursement or waiver arrangements can decrease expenses and boost performance.

Fund Distribution

The fund is composed of multiple classes of shares. All classes of the fund have a common investment objective and investment portfolio.

FDC distributes Class A, Class M, Class C, Class I, and Class Z shares.

Intermediaries may receive from the Adviser, FDC, and/or their affiliates compensation for their services intended to result in the sale of class shares, including compensation for providing recordkeeping and administrative services, as well as other retirement plan expenses for Class Z shares.

This may take the form of (as applicable):

Sales charges and concessions (not applicable to Class I and Class Z shares).
Distribution and/or service (12b-1) fees (not applicable to Class I and Class Z shares).
Finder's fees (not applicable to Class C, Class I, and Class Z shares).
Payments for additional distribution-related activities and/or shareholder services.
Payments for educational seminars and training, including seminars sponsored by Fidelity, or by an intermediary.

These payments are described in more detail in this section and in the SAI.

Please speak with your investment professional to learn more about any payments his or her firm may receive from the Adviser, FDC, and/or their affiliates, as well as fees and/or commissions the investment professional charges. You should also consult disclosures made by your investment professional at the time of purchase.

You may pay a sales charge when you buy or sell your Class A, Class M, and Class C shares.

FDC collects the sales charge.

As described in detail in this section, you may be entitled to a waiver of your sales charge, or to pay a reduced sales charge, when you buy or sell Class A, Class M, and Class C shares. In the event of changes in sales charges, sales charges, if any, in effect at the time of purchase generally will apply.

The availability of certain sales charge waivers and discounts may depend on whether you purchase your shares directly from a fund or through an intermediary. Intermediaries may have different policies and procedures regarding the availability of front-end sales load waivers or CDSC (back-end) waivers. Please see "Sales Charge Waiver Policies Applied by Certain Intermediaries" in the "Appendix" section of the prospectus. In all instances, it is the purchaser's responsibility to notify a fund or the purchaser's intermediary at the time of purchase of any relationship or other facts qualifying the purchaser for sales charge waivers or discounts. For waivers and discounts not available through a particular intermediary, shareholders will have to purchase fund shares directly from a fund or through another intermediary to receive these waivers or discounts.

The front-end sales charge will be reduced for purchases of Class A and Class M shares according to the sales charge schedules below.

Class A or Class M shares purchased by an individual or company through the Combined Purchase, Rights of Accumulation, or Letter of Intent program may receive a reduced front-end sales charge according to the sales charge schedules above. To qualify for a Class A or Class M front-end sales charge reduction under one of these programs, you must notify Fidelity in advance of your purchase.

Combined Purchase, Rights of Accumulation, and Letter of Intent Programs. The following qualify as an "individual" or "company" for the purposes of determining eligibility for the Combined Purchase and Rights of Accumulation program: an individual, spouse, and their children under age 21 purchasing for his/her or their own account; a trustee, administrator, or other fiduciary purchasing for a single trust estate or a single fiduciary account or for a single or parent-subsidiary group of "employee benefit plans" (except SEP and SARSEP plans and plans covering self-employed individuals and their employees (formerly Keogh/H.R. 10 plans)) and 403(b) programs; and tax-exempt organizations (as defined in Section 501(c)(3) of the Internal Revenue Code). The following qualify as an "individual" or "company" for the purposes of determining eligibility for the Letter of Intent program: an individual, spouse, and their children under age 21 purchasing for his/her or their own account; a trustee, administrator, or other fiduciary purchasing for a single trust estate or a single fiduciary account (except SEP and SARSEP plans and plans covering self-employed individuals and their employees (formerly Keogh/H.R. 10 plans)); an IRA or plans covering sole-proprietors (formerly Keogh/H.R. 10 plans); plans investing through the Fidelity Advisor® 403(b) program; and tax-exempt organizations (as defined in Section 501(c)(3) of the Internal Revenue Code).

Combined Purchase. To receive a Class A or Class M front-end sales charge reduction, if you are a new shareholder, you may combine your purchase of Class A or Class M shares with purchases of: (i) Class A, Class M, and Class C shares of any Fidelity® fund that offers Advisor classes of shares, (ii) Advisor C Class shares of Fidelity® Treasury Money Market Fund, and (iii) Class A Units (New and Old), Class C Units, Class D Units, and Class P Units of the Fidelity Advisor® 529 Plan. Purchases may be aggregated across multiple intermediaries on the same day for the purpose of qualifying for the Combined Purchase program.

Rights of Accumulation. To receive a Class A or Class M front-end sales charge reduction, if you are an existing shareholder, you may add to your purchase of Class A or Class M shares the current value of your holdings in: (i) Class A, Class M, and Class C shares of any Fidelity® fund that offers Advisor classes of shares, (ii) Advisor C Class shares of Fidelity® Treasury Money Market Fund, (iii) Daily Money Class shares of a fund that offers Daily Money Class shares acquired by exchange from any Fidelity® fund that offers Advisor classes of shares, (iv) Class O shares of Fidelity Advisor® Diversified Stock Fund and Fidelity Advisor® Capital Development Fund, and (v) Class A Units (New and Old), Class C Units, Class D Units, and Class P Units of the Fidelity Advisor® 529 Plan. The current value of your holdings is determined at the NAV at the close of business on the day prior to your purchase of Class A or Class M shares. The current value of your holdings will be added to your purchase of Class A or Class M shares for the purpose of qualifying for the Rights of Accumulation program. Purchases and holdings may be aggregated across multiple intermediaries for the purpose of qualifying for the Rights of Accumulation program.

Letter of Intent. You may receive a Class A or Class M front-end sales charge reduction on your purchases of Class A and Class M shares made during a 13-month period by signing a Letter of Intent (Letter). File your Letter with Fidelity no later than the date of the initial purchase toward completing your Letter. Each Class A or Class M purchase you make toward completing your Letter will be entitled to the reduced front-end sales charge applicable to the total investment indicated in the Letter. Purchases of the following may be aggregated for the purpose of completing your Letter: (i) Class A and Class M shares of any Fidelity® fund that offers Advisor classes of shares (except those acquired by exchange from Daily Money Class shares of a fund that offers Daily Money Class shares that had been previously exchanged from a Fidelity® fund that offers Advisor classes of shares), (ii) Class C shares of any Fidelity® fund that offers Advisor classes of shares, (iii) Advisor C Class shares of Fidelity® Treasury Money Market Fund, and (iv) Class A Units (New and Old), Class C Units, Class D Units, and Class P Units of the Fidelity Advisor® 529 Plan. Reinvested income and capital gain distributions will not be considered purchases for the purpose of completing your Letter. Purchases may be aggregated across multiple intermediaries for the purpose of qualifying for the Letter of Intent program. Your initial purchase toward completing your Letter must be at least 5% of the total investment specified in your Letter. Fidelity will register Class A or Class M shares equal to 5% of the total investment specified in your Letter in your name and will hold those shares in escrow. You will earn income, dividends and capital gain distributions on escrowed Class A and Class M shares. The escrow will be released when you complete your Letter. You are not obligated to complete your Letter. If you do not complete your Letter, you must pay the increased front-end sales charges due in accordance with the sales charge schedule in effect when your shares were originally bought. Fidelity may redeem sufficient escrowed Class A or Class M shares to pay any applicable front-end sales charges. If you purchase more than the amount specified in your Letter and qualify for additional Class A or Class M front-end sales charge reductions, the front-end sales charge will be adjusted to reflect your total purchase at the end of 13 months and the surplus amount will be applied to your purchase of additional Class A or Class M shares at the then-current offering price applicable to the total investment.

Detailed information about these programs also is available on institutional.fidelity.com. In order to obtain the benefit of a front-end sales charge reduction for which you may be eligible, you may need to inform your investment professional of other accounts you, your spouse, or your children maintain with your investment professional or other investment professionals from the same intermediary.

Class C shares may, upon redemption less than one year after purchase, for any reason, be assessed a CDSC of 1.00%. The actual CDSC you pay may be higher or lower than that calculated using this percentage due to rounding. The impact of rounding may vary with the amount of your investment and the size of the class's NAV.

Investment professionals will receive as compensation from FDC, at the time of the sale, a concession equal to 1.00% of your purchase of Class C shares. A concession will not apply to Class C shares acquired through reinvestment of dividends or capital gain distributions.

The CDSC for Class A, Class M, and Class C shares will be calculated based on the lesser of the cost of each class's shares, as applicable, at the initial date of purchase or the value of those shares, as applicable, at redemption, not including any reinvested dividends or capital gains. Class A, Class M, and Class C shares acquired through reinvestment of dividends or capital gain distributions will not be subject to a CDSC. In determining the applicability and rate of any CDSC at redemption, shares representing reinvested dividends and capital gains will be redeemed first, followed by those shares that have been held for the longest period of time.

A front-end sales charge will not apply to the following Class A or Class M shares:

1. Purchased for an employee benefit plan other than a plan investing through the Fidelity Advisor® 403(b) program.

Finder's Fees. Finder's fees may be paid to investment professionals who sell Class A and Class M shares in purchase amounts of $1 million or more. For Class A share purchases, investment professionals may be compensated at the time of purchase with a finder's fee at the rate of 0.75% of the purchase amount for purchases of $1 million up to $4 million, 0.50% of the purchase amount for purchases of $4 million up to $25 million, and 0.25% of the purchase amount for purchases of $25 million or more. For Class M share purchases, investment professionals may be compensated at the time of purchase with a finder's fee at the rate of 0.25% of the purchase amount.

Investment professionals may be eligible for a finder's fee on the following purchases of Class A and Class M shares made through broker-dealers and banks: a trade that brings the value of the accumulated account(s) of an investor, including a 403(b) program or an employee benefit plan (except a SEP or SARSEP plan or a plan covering self-employed individuals and their employees (formerly a Keogh/H.R. 10 plan)), over $1 million; a trade for an investor with an accumulated account value of $1 million or more; and an incremental trade toward an investor's $1 million Letter.

Accumulated account value for purposes of finder's fees eligibility is determined the same as it is for Rights of Accumulation. Daily Money Class shares of a fund that offers Daily Money Class shares are not counted for this purpose unless acquired by exchange from any Fidelity® fund that offers Advisor classes of shares. For information, see "Combined Purchase, Rights of Accumulation, and Letter of Intent Programs" above.

Finder's fees are not paid in connection with purchases of Class A or Class M shares by insurance company separate accounts or managed account programs that charge an asset-based fee, or purchases of Class A or Class M shares made with the proceeds from the redemption of shares of any Fidelity® fund or any retirement plan recordkept at Fidelity.

Investment professionals should contact Fidelity in advance to determine if they qualify to receive a finder's fee. Finder's fees will be paid in connection with shares recordkept in a Fidelity Advisor® 401(k) Retirement Plan only at the time of the initial conversion of assets. Investment professionals should contact Fidelity for more information.

Reinstatement Privilege. If you have sold all or part of your Class A, Class M, or Class C shares of the fund, you may reinvest an amount equal to all or a portion of the redemption proceeds in the same class of the fund or another Fidelity® fund that offers Advisor classes of shares, at the NAV next determined after receipt in proper form of your investment order, provided that such reinvestment is made within 90 days of redemption. Under these circumstances, the dollar amount of the CDSC you paid, if any, on shares will be reimbursed to you by reinvesting that amount in Class A, Class M, or Class C shares, as applicable.

You must reinstate your shares into an account with the same registration. This privilege may be exercised only once by a shareholder with respect to the fund and certain restrictions may apply. For purposes of the CDSC schedule, the holding period will continue as if the Class A, Class M, or Class C shares had not been redeemed. To qualify for the reinstatement privilege, you must notify Fidelity in writing in advance of your reinvestment.

Distribution and Service Plan(s)

Class A of the fund has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. Under the plan, Class A of the fund is authorized to pay FDC a monthly 12b-1 (distribution) fee as compensation for providing services intended to result in the sale of Class A shares. Class A of the fund may pay this 12b-1 (distribution) fee at an annual rate of 0.15% of its average net assets, or such lesser amount as the Trustees may determine from time to time. Currently, the Trustees have not approved such payments. The Trustees may approve 12b-1 (distribution) fee payments at an annual rate of up to 0.15% of Class A's average net assets when the Trustees believe that it is in the best interests of Class A shareholders to do so.

In addition, pursuant to the Class A plan, Class A of the fund pays FDC a monthly 12b-1 (service) fee at an annual rate of 0.25% of Class A's average net assets throughout the month for providing shareholder support services.

Except as provided below, FDC may reallow up to the full amount of this 12b-1 (service) fee to intermediaries, including its affiliates, for providing shareholder support services.

For purchases of Class A shares on which a finder's fee was paid to intermediaries, after the first year of investment, FDC may reallow up to the full amount of the 12b-1 (service) fee paid by such shares to intermediaries, including its affiliates, for providing shareholder support services.

Class M of the fund has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. Under the plan, Class M of the fund is authorized to pay FDC a monthly 12b-1 (distribution) fee as compensation for providing services intended to result in the sale of Class M shares. Class M of the fund may pay this 12b-1 (distribution) fee at an annual rate of 0.15% of its average net assets, or such lesser amount as the Trustees may determine from time to time. Currently, the Trustees have not approved such payments. The Trustees may approve 12b-1 (distribution) fee payments at an annual rate of up to 0.15% of Class M's average net assets when the Trustees believe that it is in the best interests of Class M shareholders to do so.

In addition, pursuant to the Class M plan, Class M of the fund pays FDC a monthly 12b-1 (service) fee at an annual rate of 0.25% of Class M's average net assets throughout the month for providing shareholder support services.

FDC may reallow up to the full amount of this 12b-1 (service) fee to intermediaries, including its affiliates, for providing shareholder support services.

Class C of the fund has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. Under the plan, Class C of the fund is authorized to pay FDC a monthly 12b-1 (distribution) fee as compensation for providing services intended to result in the sale of Class C shares. Class C of the fund currently pays FDC a monthly 12b-1 (distribution) fee at an annual rate of 0.75% of its average net assets throughout the month.

In addition, pursuant to the Class C plan, Class C of the fund pays FDC a monthly 12b-1 (service) fee at an annual rate of 0.25% of Class C's average net assets throughout the month for providing shareholder support services.

Normally, after the first year of investment, FDC may reallow up to the full amount of the 12b-1 (distribution) fees to intermediaries, including its affiliates, for providing services intended to result in the sale of Class C shares and may reallow up to the full amount of the 12b-1 (service) fee to intermediaries, including its affiliates, for providing shareholder support services.

For purchases of Class C shares made through reinvestment of dividends or capital gain distributions, during the first year of investment and thereafter, FDC may reallow up to the full amount of this 12b-1 (distribution) fee paid by such shares to intermediaries, including its affiliates, for providing services intended to result in the sale of Class C shares and may reallow up to the full amount of this 12b-1 (service) fee paid by such shares to intermediaries, including its affiliates, for providing shareholder support services.

Any fees paid out of Class A's, Class M's, and Class C's assets on an ongoing basis pursuant to a Distribution and Service Plan will increase the cost of your investment and may cost you more than paying other types of sales charges.

In addition to the above payments, each Class A, Class M, and Class C plan specifically recognizes that the Adviser may make payments from its management fee revenue, past profits, or other resources to FDC for expenses incurred in connection with providing services intended to result in the sale of Class A, Class M, and Class C shares and/or shareholder support services. The Adviser, directly or through FDC or one or more affiliates, may pay significant amounts to intermediaries that provide those services. Currently, the Board of Trustees of the fund has authorized such payments for Class A, Class M, and Class C.

Each of Class I and Class Z of the fund has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act that recognizes that the Adviser may use its management fee revenues, as well as its past profits or its resources from any other source, to pay FDC for expenses incurred in connection with providing services intended to result in the sale of Class I and Class Z shares and/or shareholder support services. The Adviser, directly or through FDC, may pay significant amounts to intermediaries that provide those services. Currently, the Board of Trustees of the fund has authorized such payments for Class I and Class Z.

If payments made by the Adviser to FDC or to intermediaries under Class I's and Class Z's Distribution and Service Plan were considered to be paid out of Class I's and Class Z's assets on an ongoing basis, they would increase the cost of your investment and might cost you more than paying other types of sales charges.

Edward D. Jones & Co., L.P. ("Edward Jones")

Policies Regarding Transactions Through Edward Jones

The following information has been provided by Edward Jones:

The following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as "shareholders") purchasing fund shares on the Edward Jones commission and fee-based platforms are eligible only for the following sales charge discounts (also referred to as "breakpoints") and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund prospectus or statement of additional information ("SAI") or through another broker-dealer. In all instances, it is the shareholder's responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of the fund family, or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.

Breakpoints

• Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the prospectus.

Rights of Accumulation ("ROA")

The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of the mutual fund family held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations ("pricing groups"). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge.
The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.
ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).

Letter of Intent ("LOI")

Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. The inclusion of eligible fund family assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales charges will be adjusted if LOI is not met.

If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.

Sales Charge Waivers

Sales charges are waived for the following shareholders and in the following situations:

Associates of Edward Jones and its affiliates and other accounts in the same pricing group (as determined by Edward Jones under its policies and procedures) as the associate. This waiver will continue for the remainder of the associate's life if the associate retires from Edward Jones in good-standing and remains in good standing pursuant to Edward Jones' policies and procedures.
Shares purchased in an Edward Jones fee-based program.
Shares purchased through reinvestment of capital gains distributions and dividend reinvestment.
Shares purchased from the proceeds of redeemed shares of the same fund family so long as the following conditions are met: the proceeds are from the sale of shares within 60 days of the purchase, the sale and purchase are made from a share class that charges a front load and one of the following ("Right of Reinstatement"):

The redemption and repurchase occur in the same account.
The redemption proceeds are used to process an: IRA contribution, excess contributions, conversion, recharacterizing of contributions, or distribution, and the repurchase is done in an account within the same Edward Jones grouping for ROA.

The Right of Reinstatement excludes systematic or automatic transactions including, but not limited to, purchases made through payroll deductions, liquidations to cover account fees, and reinvestments from non-mutual fund products.

Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of Edward Jones. Edward Jones is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus.
Exchanges from Class C shares to Class A shares of the same fund, generally, in the 84th month following the anniversary of the purchase date or earlier at the discretion of Edward Jones.

Contingent Deferred Sales Charge ("CDSC") Waivers

If the shareholder purchases shares that are subject to a CDSC and those shares are redeemed before the CDSC is expired, the shareholder is responsible to pay the CDSC except in the following conditions:

The death or disability of the shareholder.
Systematic withdrawals with up to 10% per year of the account value.
Return of excess contributions from an Individual Retirement Account (IRA).
Shares redeemed as part of a required minimum distribution for IRA and retirement accounts if the redemption is taken in or after the year the shareholder reaches qualified age based on applicable IRS regulations.
Shares redeemed to pay Edward Jones fees or costs in such cases where the transaction is initiated by Edward Jones.
Shares exchanged in an Edward Jones fee-based program.
Shares acquired through NAV reinstatement.
Shares redeemed at the discretion of Edward Jones for Minimum Balances, as described below.

PFS Investments Inc. ("PFSI")

Policies Regarding Transactions Through PFSI

The following information supersedes all prior information with respect to transactions and positions held in fund shares purchased through PFSI and held on the mutual fund platform of its affiliate, Primerica Shareholder Services ("PSS"). Clients of PFSI (also referred to as "shareholders") purchasing fund shares on the PSS platform are eligible only for the following share classes, sales charge discounts (also referred to as "breakpoints") and waivers, which can differ from share classes, discounts and waivers described elsewhere in this prospectus or the related statement of additional information ("SAI") or through another broker-dealer.

Share Classes

Class A shares: in non-retirement accounts, individual retirement accounts (IRA), SEP IRAs, SIMPLE IRAs, Keogh Plans, and all other account types unless expressly provided for below.

Class C shares: only in accounts with existing Class C share holdings.

Breakpoints

Breakpoint pricing at dollar thresholds as described in the prospectus of the fund you are purchasing.

Rights of Accumulation ("ROA")

The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except any assets held in group retirement plans) of Fidelity Advisor Funds held by the shareholder on the PSS platform.

It is the shareholder's responsibility to inform PFSI of all eligible fund family assets at the time of calculation. Shares of money market funds are included only if such shares were acquired in exchange for shares of another Fidelity Advisor Fund purchased with a sales charge. No shares of Fidelity Advisor Funds held by the shareholder away from the PSS platform will be granted ROA with shares of any Fidelity Advisor Fund purchased on the PSS platform.

Any SEP IRA plan, any SIMPLE IRA plan or any Payroll Deduction plan ("PDP") on the PSS platform will be defaulted to plan-level grouping for purposes of ROA, which allows each participating employee ROA with all other eligible shares held in plan accounts on the PSS platform. At any time, a participating employee may elect to exercise a one-time option to change grouping for purposes of ROA to shareholder-level grouping, which allows the plan account of the electing employee ROA with other eligible holdings on the PSS platform, but not with all other eligible participant holdings in the plan. Eligible shares held in plan accounts electing shareholder-level grouping will not be available for purposes of ROA to plan accounts electing plan-level grouping.

ROA is determined by calculating the higher of cost minus redemptions or current market value (current shares x NAV).

Letter of Intent ("LOI")

By executing a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period, through PFSI, from the date PSS receives the LOI. The purchase price of the LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the dollar amount the shareholder intends to invest over a 13-month period to arrive at total investment for purposes of determining any breakpoint discount and the applicable front-end sales charge. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the projected total investment.

Only holdings of Fidelity Advisor Funds on the PSS platform are eligible for inclusion in the LOI calculation and the shareholder must notify PFSI of all eligible assets at the time of calculation. It is the shareholder's responsibility to inform PFSI at the time of a purchase of all holdings of Fidelity Advisor Funds on the PSS platform, or other facts qualifying the purchaser for this discount.

Purchases made before the LOI is received by PSS are not adjusted under the LOI, and the LOI will not reduce any sales charge previously paid. Sales charges will be automatically adjusted if the total purchases required by the LOI are not met.

If an employer maintaining a SEP IRA plan, SIMPLE IRA plan or non-IRA PDP on the PSS platform has elected to establish or change ROA for the accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer. LOIs are not available to PDP IRA plans on the PSS platform with plan-level grouping for purposes of ROA but are available to any participating employee that elects shareholder-level grouping for purposes of ROA.

Sales Charge Waivers

Sales charges are waived for the following shareholders and in the following situations:

Shares purchased through reinvestment of capital gains distributions and dividend reinvestment.

Shares purchased with the proceeds of redeemed shares of the same fund family so long as the following conditions are met: 1) the proceeds are from the sale of shares within 90 days of the purchase, 2) the sale and purchase are made in the same share class and the same account or the purchase is made in an individual retirement account with proceeds from liquidations in a non-retirement account, and 3) the redeemed shares were subject to a front-end or deferred sales load. Automated transactions (i.e., systematic purchases and withdrawals), full or partial transfers or rollovers of retirement accounts, and purchases made after shares are automatically sold to pay account maintenance fees are not eligible for this sales charge waiver.

Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of PFSI. PFSI is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus.

Policies Regarding Fund Purchases Through PFSI That Are Not Held on the PSS Platform

Class R shares are available through PFSI only in 401(k) plans covering a business owner with no employees, commonly referred to as a one-participant 401(k) plan or solo 401(k).

PFSI may request reasonable documentation of facts qualifying the purchaser for the discounts and waivers identified above, and condition the granting of any discount or waiver on the timely receipt of such documents. Shareholders should contact PSS if they have questions regarding their eligibility for these discounts and waivers.

Principal Investment Strategies

Normally investing at least 80% of assets in municipal securities (i) whose interest is exempt from federal income tax and (ii) that Fidelity Management & Research Company LLC (FMR) (the Adviser) believes have positive environmental, social and governance (ESG) characteristics. The municipal securities in which the fund invests are normally investment-grade (those of medium and high quality).

Evaluating each security in which the fund invests using both a traditional municipal bond credit, structure and relative value analysis and a consideration of the Adviser's judgment about the security's ESG characteristics. When assessing a security's ESG characteristics and its eligibility for purchase, the Adviser considers the following, where available: (i) the sustainability practices of the security's issuer or obligor, as applicable (each, an "issuer"), based on an evaluation of such issuer's individual ESG profile; (ii) information on a security's use of proceeds; and (iii) any third-party designation as a green, sustainable or sustainability-linked bond. A security's positive ESG characteristics can be determined under any of those three factors.
Using the Adviser's proprietary ESG ratings process to evaluate the current state of an issuer's sustainability practices using a data-driven framework that includes both proprietary and third-party data, and also provide a qualitative forward-looking assessment of an issuer's sustainability outlook provided by the Adviser's fundamental research analysts and ESG team.
The Adviser's ESG ratings of issuers are derived from multiple factors, including an issuer's environmental profile, which may include, but is not limited to, carbon and toxic emissions, water management, waste management, and vulnerability to the physical impacts of climate change. An assessment of an issuer's social profile includes, but is not limited to, its approach to quality health care access, housing affordability, human capital management, community reinvestment, and safety. An assessment of an issuer's governance profile includes, but is not limited to, its principles of management, oversight and transparency, governance efficiency and structure, and consideration of anticompetitive practices. These factors are weighted based on how material the Adviser believes each factor is to an issuer's financial outlook, effectiveness at service delivery, and long-term sustainability, and not all factors may be applicable to all issuers. Issuers with an above average ESG rating as determined by the Adviser are considered to have positive ESG characteristics and well-managed ESG risks.
Assessing a security's use of proceeds by considering factors that provide ESG characteristics, such as energy efficiency, environmentally sustainable management, and providing access to quality health care, essential services and affordable housing. The Adviser will generally consider bonds that finance education, health care, affordable housing, clean energy, municipal water and sewer, public transportation, and designated green bonds, among others, as having positive ESG characteristics.
Managing the fund to have similar overall interest rate risk to the supplemental index (see "Additional Index Information" section of the prospectus).
In addition to focusing on municipal securities with positive ESG characteristics, the Adviser analyzes the credit quality of the issuer, security-specific features, current and potential future valuation, and trading opportunities to select investments.
Normally maintaining a dollar-weighted average maturity between three and 10 years.
Allocating assets across different market sectors and maturities.
Potentially investing more than 25% of total assets in municipal securities that finance similar types of projects.
Employing sustainable investing exclusion criteria to avoid investments in issuers that are directly engaged in, and/or derive significant revenue from, certain industries. Please see "Fund Basics - Investment Details - Sustainable Investing Exclusions" for additional information.

Principal Investment Risks

Municipal Market Volatility.

The municipal market is volatile and can be significantly affected by adverse tax, legislative, or political changes and the financial condition of the issuers of municipal securities.

Sustainability Risk.

Interest Rate Changes.

Interest rate increases can cause the price of a debt security to decrease.

Issuer-Specific Changes.

The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

Management Risk.

Unlike individual debt securities, which typically pay principal at maturity, the value of an investment in the fund will fluctuate.

Portfolio Manager(s)

The Statement of Additional Information (SAI) provides additional information about the compensation of, any other accounts managed by, and any fund shares held by the portfolio manager(s).

Advisory Fee(s)

Each class of the fund pays a management fee to the Adviser.

The management fee is calculated and paid to the Adviser every month.

The annual management fee rate for the class of shares of the fund offered through this prospectus is the lesser of (1) the class's mandate rate reduced by the class's discount rate (if applicable) or (2) the amount listed below:

Fund	Retail Class
Fidelity® Sustainable Intermediate Municipal Income Fund	0.43%

One-twelfth of the management fee rate for a class is applied to the average net assets of the class for the month, giving a dollar amount which is the management fee for the class for that month.

The management fee, as a percentage of the class's average net assets, for the fiscal year ended January 31, 2025, for the fund is shown in the following table. Because a class's management fee rate may fluctuate, a class's management fee may be higher or lower in the future.

Fund/Class	Management Fee Rate

The Adviser pays FMR Investment Management (UK) Limited, Fidelity Management & Research (Hong Kong) Limited, and Fidelity Management & Research (Japan) Limited for providing sub-advisory services.

Reimbursement or waiver arrangements can decrease expenses and boost performance.

Fund Distribution

The fund is composed of multiple classes of shares. All classes of the fund have a common investment objective and investment portfolio.

FDC distributes the fund's shares.

Intermediaries may receive from the Adviser, FDC, and/or their affiliates compensation for providing recordkeeping and administrative services, as well as other retirement plan expenses, and compensation for services intended to result in the sale of fund shares.

These payments are described in more detail in this section and in the SAI.

Distribution and Service Plan(s)

The fund has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940 (1940 Act) with respect to its shares that recognizes that the Adviser may use its management fee revenues, as well as its past profits or its resources from any other source, to pay FDC for expenses incurred in connection with providing services intended to result in the sale of shares of the fund and/or shareholder support services. The Adviser, directly or through FDC, may pay significant amounts to intermediaries that provide those services. Currently, the Board of Trustees of the fund has authorized such payments for shares of the fund.

If payments made by the Adviser to FDC or to intermediaries under the Distribution and Service Plan were considered to be paid out of the class's assets on an ongoing basis, they would increase the cost of your investment and might cost you more than paying other types of sales charges.

From time to time, FDC may offer special promotional programs to investors who purchase shares of Fidelity® funds. For example, FDC may offer merchandise, discounts, vouchers, or similar items to investors who purchase shares of certain Fidelity® funds during certain periods. To determine if you qualify for any such programs, contact Fidelity or visit our web site at www.fidelity.com.

Principal Investment Strategies

Normally investing at least 80% of assets in U.S. dollar-denominated municipal money market securities and high quality investment-grade municipal debt securities (i) whose interest is exempt from federal income tax and (ii) that Fidelity Management & Research Company LLC (FMR) (the Adviser) believes have positive environmental, social and governance (ESG) characteristics.

Municipal money market securities are high-quality, short-term debt securities that pay a fixed, variable, or floating interest rate, and include variable rate demand notes, commercial paper, and municipal notes. Municipal securities are issued to raise money for a variety of public and private purposes, including general financing for state and local governments, financing for eligible non-profit organizations, or financing for a specific project or public facility.

High quality investment grade securities in which the fund invests include securities or issuers (i) rated at least A- or its equivalent by at least one nationally recognized statistical ratings organization (NRSRO) or similarly rated by the Adviser, and (ii) for securities with a credit maturity within one year, rated at least BBB or its equivalent by all NRSROs that rate the security and similarly rated by the Adviser.

Evaluating each security in which the fund invests using both a traditional municipal bond credit, structure and relative value analysis and a consideration of the Adviser's judgment about the security's ESG characteristics. When assessing a security's ESG characteristics and its eligibility for purchase, the Adviser considers the following, where available: (i) the sustainability practices of the security's issuer or obligor, as applicable (each, an "issuer"), based on an evaluation of such issuer's individual ESG profile; (ii) information on a security's use of proceeds; and (iii) any third-party designation as a green, sustainable or sustainability-linked bond. A security's positive ESG characteristics can be determined under any of those three factors.
Using the Adviser's proprietary ESG ratings process to evaluate the current state of an issuer's sustainability practices using a data-driven framework that includes both proprietary and third-party data, and also provide a qualitative forward-looking assessment of an issuer's sustainability outlook provided by the Adviser's fundamental research analysts and ESG team.
The Adviser's ESG ratings of issuers are derived from multiple factors, including an issuer's environmental profile, which may include, but is not limited to, carbon and toxic emissions, water management, waste management, and vulnerability to the physical impacts of climate change. An assessment of an issuer's social profile includes, but is not limited to, its approach to quality health care access, housing affordability, human capital management, community reinvestment, and safety. An assessment of an issuer's governance profile includes, but is not limited to, its principles of management, oversight and transparency, governance efficiency and structure, and consideration of anticompetitive practices. These factors are weighted based on how material the Adviser believes each factor is to an issuer's financial outlook, effectiveness at service delivery, and long-term sustainability, and not all factors may be applicable to all issuers. Issuers with an above average ESG rating as determined by the Adviser are considered to have positive ESG characteristics and well-managed ESG risks.
Assessing a security's use of proceeds by considering factors that provide ESG characteristics, such as energy efficiency, environmentally sustainable management, and providing access to quality health care, essential services and affordable housing. The Adviser will generally consider bonds that finance education, health care, affordable housing, clean energy, municipal water and sewer, public transportation, and designated green bonds, among others, as having positive ESG characteristics.
Managing the fund to have similar overall interest rate risk to the supplemental index (see "Additional Index Information" section of the prospectus).
In addition to focusing on municipal securities with positive ESG characteristics, the Adviser analyzes the credit quality of the issuer, security-specific features, current and potential future valuation, and trading opportunities to select investments.
Normally maintaining a dollar-weighted average maturity of one year or less.
Normally investing in securities with a maximum maturity of four years.
Allocating assets across different market sectors and maturities.
Potentially investing more than 25% of total assets in municipal securities that finance similar types of projects.
Employing sustainable investing exclusion criteria to avoid investments in issuers that are directly engaged in, and/or derive significant revenue from, certain industries. Please see "Fund Basics - Investment Details - Sustainable Investing Exclusions" for additional information.

Principal Investment Strategies

Normally investing at least 80% of assets in municipal securities (i) whose interest is exempt from federal income tax and (ii) that Fidelity Management & Research Company LLC (FMR) (the Adviser) believes have positive environmental, social and governance (ESG) characteristics.

Description of Principal Security Types

In addition to the security types discussed above, the following describes the types of securities in which a fund invests or may invest principally:

Sustainable Investing Exclusions

As part of its investment approach, a fund also applies broad criteria ("exclusion criteria") that seek to exclude issuers that are directly engaged in, and/or derive significant revenue from, certain industries or product lines. At present, these include: civilian semi-automatic firearms; tobacco production, or bonds issued against the proceeds of tobacco settlements; for-profit prisons; controversial weapons (e.g., cluster munitions, land mines, biological/chemical weapons, blinding lasers, and incendiary weapons); and thermal coal production and/or mining.

In determining whether an issuer is directly engaged in, and/or derives significant revenue from a particular industry or product line, a fund may use revenue thresholds (e.g., issuers that derive more than 5% of revenue from thermal coal production and/or mining) and/or categorical exclusions (e.g., issuers that derive any revenue from the operation of private prisons), depending on the industry or product line. The exclusion criteria are based in whole or in part on data provided by one or more third-party vendor(s) and are, therefore, subject to each vendor's industry and product line definitions (which may vary from those of the Adviser) and data limitations. The Adviser, in its sole discretion, retains the right not to use data provided by third-party vendors where it deems the data not representative of an issuer's current business operations. In such cases, or where data on specific issuers may not be available from third-party vendors, the Adviser may make reasonable estimates or otherwise exercise its discretion.

A fund's exclusion criteria may be updated periodically to, among other things, add or remove certain industries or product lines from the screening process, revise the revenue thresholds and categorical exclusions applicable to such activities, or change particular industries or product lines from a categorical exclusion to a revenue threshold, or vice versa. Once the Adviser determines that an issuer is not subject to the fund's exclusion criteria, the Adviser then employs the sustainability strategy discussed above. In addition, a fund may invest in third-party investment products (e.g., mutual funds, ETFs, and/or index futures) that apply different or no exclusion criteria or sustainable investment strategies.

The implementation of the sustainability strategy (or strategies) is conducted alongside traditional fundamental, bottom-up financial analysis of individual issuers, using traditional fundamental metrics and/or traditional quantitative metrics. The Adviser may also engage in dialogues with the issuer's management teams to further inform investment decision-making and to foster best corporate governance practices using its fundamental and sustainability analysis. In addition, a fund may invest in an issuer prior to completion of the sustainability analysis or without engaging with the issuer's management.

Principal Investment Risks

Many factors affect each fund's performance. Developments that disrupt global economies and financial markets, such as public health emergencies, military conflicts, terrorism, government restrictions, political changes, and environmental disasters, may significantly affect a fund's investment performance.

A fund's NAV change daily based on changes in market conditions and interest rates and in response to other economic, political, or financial developments. A fund's reaction to these developments will be affected by the types of securities in which the fund invests, the financial condition, industry and economic sector, and geographic location of an issuer, and the fund's level of investment in the securities of that issuer. When your shares are sold they may be worth more or less than what you paid for them, which means that you could lose money by investing in the fund.

Unlike individual debt securities, which typically pay principal at maturity, the value of an investment in the fund will fluctuate.

The following factors can significantly affect the fund's performance:

Sustainability Risk. Application of FMR's ESG ratings process and/or its sustainable investing exclusion criteria may affect the fund's exposure to certain issuers, sectors, regions, and countries and may affect the fund's performance depending on whether certain investments are in or out of favor. The criteria related to a fund's ESG ratings process and/or adherence to its sustainable investing exclusion criteria may result in the fund forgoing opportunities to buy certain securities when it might otherwise be advantageous to do so, or selling securities for ESG reasons when it might be otherwise disadvantageous for it to do so. As a result, the fund's performance may at times be better or worse than the performance of funds that do not use ESG or sustainability criteria. There are significant differences in interpretations of what it means for an issuer to have positive ESG factors. While the Adviser believes its definitions are reasonable, the portfolio decisions it makes may differ with other investors' or advisers' views. Socially responsible norms differ by country and region, and an issuer's ESG factors or the Adviser's assessment of such may change over time. A fund may invest in issuers that do not reflect the beliefs and values of any particular investor. When conducting the ESG ratings process of an issuer or compiling and maintaining the sustainable investing exclusion list, the Adviser may rely on information or data obtained through voluntary or third-party reporting that may be incomplete, inaccurate, or unavailable, which could cause the Adviser to incorrectly assess an issuer's business practices with respect to ESG or to incorrectly include or exclude an issuer on or from its sustainable investing exclusion list. The sustainable investing exclusion list criteria are based in whole or in part on data provided by one or more third-party vendor(s) and are, therefore, subject to each vendor's industry and product line definitions (which may vary from those of the Adviser) and data limitations. Data used in applying the exclusion criteria may include inputs self-disclosed by companies as well as estimates where public disclosures are unavailable. Certain investments may be dependent on U.S. and foreign government policies, including tax incentives and subsidies, which may change without notice. A fund's investments in certain issuers may be susceptible to various factors that may impact their businesses or operations, including costs associated with government budgetary constraints that impact publicly funded projects and initiatives, the effects of general economic conditions throughout the world, increased competition from other providers of services, unfavorable tax laws or accounting policies and high leverage.

Generally, each fund purchases municipal securities whose interest, in the opinion of bond counsel, is free from federal income tax. Neither the Adviser nor the fund guarantees that this opinion is correct, and there is no assurance that the IRS will agree with bond counsel's opinion. Issuers or other parties generally enter into covenants requiring continuing compliance with federal tax requirements to preserve the tax-free status of interest payments over the life of the security. If at any time the covenants are not complied with, or if the IRS otherwise determines that the issuer did not comply with relevant tax requirements, interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued. For certain types of structured securities, the tax status of the pass-through of tax-free income may also be based on the federal tax treatment of the structure.

Management Risk. The Adviser's application of a fund's strategy criteria may not achieve its intended results. A fund could underperform in comparison to other funds with a similar benchmark or similar objectives and investment strategies.

Other Investment Strategies

In addition to the principal investment strategies discussed above, the Adviser may invest Fidelity® SAI Sustainable Conservative Income Municipal Bond Fund's assets in municipal debt securities by investing in other funds.

The Adviser may invest Fidelity® SAI Sustainable Conservative Income Municipal Bond Fund's assets in lower quality investment-grade securities.

In addition to the principal investment strategies discussed above, the Adviser may invest Fidelity® SAI Sustainable Municipal Income Fund's assets in lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds). The Adviser may invest the fund's assets in municipal debt securities by investing in other funds.

The Adviser may also engage in transactions that have a leveraging effect on a fund, including investments in derivatives, regardless of whether the fund may own the asset, instrument, or components of the index underlying the derivative, and forward-settling securities. A fund's derivative investments may include interest rate swaps, total return swaps, credit default swaps, and futures contracts (both long and short positions) on securities and indexes. Depending on the Adviser's outlook and market conditions, the Adviser may engage in these transactions to increase or decrease a fund's exposure to changing security prices, interest rates, credit qualities, or other factors that affect security values, or to gain or reduce exposure to an asset, instrument, or index.

Fundamental Investment Policies

The following is fundamental, that is, subject to change only by shareholder approval:

Fidelity® SAI Sustainable Conservative Income Municipal Bond Fund normally invests at least 80% of its assets in U.S. dollar-denominated municipal money market securities and high quality investment-grade municipal debt securities whose interest is exempt from federal income tax.

Fidelity® SAI Sustainable Municipal Income Fund normally invests at least 80% of its assets in municipal securities whose interest is exempt from federal income tax.

Non-Fundamental Investment Policies

Each fund's investment objective is non-fundamental and may be changed without shareholder approval.

Shareholder Notice

The following is subject to change only upon 60 days' prior notice to shareholders:

Fidelity® SAI Sustainable Municipal Income Fund normally invests at least 80% of its assets in municipal securities that the Adviser believes have positive ESG characteristics.

Valuing Shares

Each fund is open for business each day the NYSE is open.

The NAV is the value of a single share. Fidelity normally calculates NAV each business day as of the times noted in the table below. Each fund's assets normally are valued as of this time for the purpose of computing NAV.

Fund	NAV Calculation Times (Eastern Time)
Fidelity® SAI Sustainable Conservative Income Municipal Bond Fund	4:00 p.m.
Fidelity® SAI Sustainable Municipal Income Fund	4:00 p.m.

NAV is not calculated and a fund will not process purchase and redemption requests submitted on days when the fund is not open for business. The time at which shares are priced and until which purchase and redemption orders are accepted may be changed as permitted by the Securities and Exchange Commission (SEC).

To the extent that a fund's assets are traded in other markets on days when the fund is not open for business, the value of the fund's assets may be affected on those days. In addition, trading in some of a fund's assets may not occur on days when the fund is open for business.

NAV is calculated using the values of other open-end funds, if any, in which a fund invests (referred to as underlying funds). Shares of underlying funds are valued at their respective NAVs. Other assets are valued primarily on the basis of market quotations, official closing prices, or information furnished by a pricing service. Certain short-term securities are valued on the basis of amortized cost. If market quotations, official closing prices, or information furnished by a pricing service are not readily available or, in the Adviser's opinion, are deemed unreliable for a security, then that security will be fair valued in good faith by the Adviser in accordance with applicable fair value pricing policies. For example, if, in the Adviser's opinion, a security's value has been materially affected by events occurring before a fund's pricing time but after the close of the exchange or market on which the security is principally traded, then that security will be fair valued in good faith by the Adviser in accordance with applicable fair value pricing policies. Fair value pricing will be used for high yield debt securities when available pricing information is determined to be stale or for other reasons not to accurately reflect fair value.

Fair value pricing is based on subjective judgments and it is possible that the fair value of a security may differ materially from the value that would be realized if the security were sold.

Shareholder Information

Additional Information about the Purchase and Sale of Shares

NOT AVAILABLE FOR SALE TO THE GENERAL PUBLIC.

Shares of Fidelity® SAI Sustainable Conservative Income Municipal Bond Fund are not eligible for purchase by registered investment companies or business development companies to the extent such acquisition is in reliance on Rule 12d1-4 under the Investment Company Act of 1940.

A fund may reject for any reason, or cancel as permitted or required by law, any purchase orders.

Excessive trading of fund shares can harm shareholders in various ways, including reducing the returns to long-term shareholders by increasing costs to a fund (such as brokerage commissions or spreads paid to dealers who sell money market instruments), disrupting portfolio management strategies, and diluting the value of the shares in cases in which fluctuations in markets are not fully priced into the fund's NAV.

Because investments in each fund can only be made by the Adviser or an affiliate on behalf of its clients, the potential for excessive or short-term disruptive purchases and sales is reduced. Accordingly, the Board of Trustees has not adopted policies and procedures designed to discourage excessive trading of fund shares and each fund accommodates frequent trading.

Each fund does not place a limit on purchases or sales of fund shares by the Adviser or its affiliates. Each fund reserves the right, but does not have the obligation, to reject any purchase transaction at any time. In addition, each fund reserves the right to impose restrictions on disruptive, excessive, or short-term trading.

Each fund has no exchange privilege with any other fund.

There is no minimum balance or purchase minimum for fund shares.

The price to buy one share is its NAV. Shares are sold without a sales charge.

Shares will be bought at the NAV next calculated after an order is received in proper form.

Shares are generally available only to investors residing in the United States.

Each fund may stop offering shares completely or may offer shares only on a limited basis, for a period of time or permanently.

Under applicable anti-money laundering rules and other regulations, purchase orders may be suspended, restricted, or canceled and the monies may be withheld.

The price to sell one share is its NAV.

Shares will be sold at the NAV next calculated after an order is received in proper form.

Normally, redemptions will be processed by the next business day, but it may take up to seven days to pay the redemption proceeds if making immediate payment would adversely affect a fund.

See "Policies Concerning the Redemption of Fund Shares" below for additional redemption information.

Redemptions may be suspended or payment dates postponed when the NYSE is closed (other than weekends or holidays), when trading on the NYSE is restricted, or as permitted by the SEC.

Redemption proceeds may be paid in securities or other property rather than in cash if the Adviser determines it is in the best interests of a fund.

When you terminate your relationship with the Adviser, or one of its affiliates, your shares may be sold at the NAV next calculated, in which case proceeds from such redemption would be sent to you.

Under applicable anti-money laundering rules and other regulations, redemption requests may be suspended, restricted, canceled, or processed and the proceeds may be withheld.

If applicable, orders by funds of funds for which the Adviser or its affiliates serve as investment manager will be treated as received by the fund at the same time that the corresponding orders are received in proper form by the funds of funds.

Policies Concerning the Redemption of Fund Shares

Dividends and Capital Gain Distributions

Each fund earns interest, dividends, and other income from its investments, and distributes this income (less expenses) to shareholders as dividends. Each fund also realizes capital gains from its investments, and distributes these gains (less any losses) to shareholders as capital gain distributions.

Any dividends and capital gain distributions may be reinvested in additional shares or paid in cash.

As with any investment, your investment in a fund could have tax consequences for you.

Taxes on Distributions

Each fund seeks to earn income and pay dividends exempt from federal income tax.

If the Adviser buys shares on your behalf when a fund has realized but not yet distributed income or capital gains, you will be "buying a dividend" by paying the full price for the shares and then receiving a portion of the price back in the form of a taxable distribution.

Any taxable distributions you receive from a fund will normally be taxable to you when you receive them, regardless of your distribution option.

For each fund, if you elect to receive distributions in cash, you will receive certain December distributions in January, but those distributions will be taxable as if you received them on December 31.

Taxes on Transactions

Your redemptions may result in a capital gain or loss for federal tax purposes. A capital gain or loss on your investment in a fund generally is the difference between the cost of your shares and the price you receive when you sell them.

Reimbursement or waiver arrangements can decrease expenses and boost performance.

Fund Distribution

FDC distributes each fund's shares.

Distribution and Service Plan(s)

Each fund has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940 (1940 Act) with respect to its shares that recognizes that the Adviser may use its management fee revenues, as well as its past profits or its resources from any other source, to pay FDC for expenses incurred in connection with providing services intended to result in the sale of shares of each fund and/or shareholder support services. The Adviser, directly or through FDC, may pay significant amounts to intermediaries that provide those services. Currently, the Board of Trustees of each fund has authorized such payments for shares of each fund.

Affiliates of the Adviser may receive service fees or distribution fees or both with respect to underlying funds that participate in Fidelity's FundsNetwork®.

If payments made by the Adviser to FDC or to intermediaries under a Distribution and Service Plan were considered to be paid out of a fund's assets on an ongoing basis, they would increase the cost of your investment and might cost you more than paying other types of sales charges.

No dealer, sales representative, or any other person has been authorized to give any information or to make any representations, other than those contained in this prospectus and in the related SAI, in connection with the offer contained in this prospectus.
